I have a 4 month old female who did have the same problem when she was younger. I was told that she thinks she is the boss, and needs to be put in her place. I treated her firm but never hit her. you have to get in ther face and let them know its not ok to snarl i evened pinned her to the ground a couple times. she seems to be doing a lot better now. how is feeding her going ? growling ?

I'm not sure what you mean by snarling. There are 3 kinds of growls, but ANY GROWL IS COMPLETELY IMPERMISSIBLE. A growl means that attack is being considered. All these signs of aggression must be dealt with very firmly, or you will have an animal who is genuinely dangerous. Bloodhounds are generally quite timid, but there are exceptions everywhere. I've had experience with aggression, and you are fortunate that he is still young. Once the animal is an adult, aggression is very difficult to control. Just yell NO! when he snarls, and if necessary, you can accompany it with a light smack if he is really recalcitrant. And you must do this EVERY TIME he snarls, or he will continually try to do it again. That is what is meant by "consistency in training." And the Bloodhound needs this type of training in all aspects. Any time you permit a command to be ignored, or snarling to occur, the dog thinks that sometimes it's allowed, sometimes not. So you must be consistent. Good Luck.
